Answer:
Step-by-step explanation:
hello :
ax+b =4x+9 so a=4 and b=9
2 1/2 x 3 = 7 1/2 = 7 4/8
10 11/8
- 7 4/8
3 7/8
A is the correct answer
<h3>Given :-</h3>
- Pranav ran 20.3 km more than Branda
To find :
- No. of kilometers did Brenda run.
<h3>Let :</h3>
- No. of kilometers ran by Brenda be x.
<h3>Solution:</h3>
Equation formed:-
Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.
Therefore:-
Write the equation
When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)
Arrange the equation because x is always represented at left side.
After subtracting 38.6 with 20.3 we will get result as 18.3 .
Answer:
△PQR and △RST are not similar.
Step-by-step explanation:
In triangle △PQR, two known interior angles are 34° and 80°. So the measure of third angle is
In triangle △RST, two known interior angles are 24° and 90°.
Two triangles are similar if their corresponding angles are same and the corresponding sides are proportional.
Since the angles of △PQR and △RST are not same, therefore we can say that the △PQR and △RST are not similar.
